Suing Apple seems to be the thing to do these days. While the company is locked into a furious, seemingly-unending battle with Samsung, another suit has been announced today by two Swiss sister companies called OpenTV and Nagravision.

According to a press release by the The Kudelski Group, the parent company of the two filing suit, OpenTV focuses on software that includes “advanced program guides, video-on-demand, personal video recording, interactive and addressable advertising and a variety of enhanced television applications,” while Nagravision “provides security and multiscreen user experience solutions for the monetization of digital media.”

While the five patents in question aren’t specifically named in the press release, it’s safe to assume that they are related to video playback technologies included in OS X and iOS (both of which are named as infringing in the press release). iAds, iTunes, the App Store, and the Apple TV are also listed.
